• I have read the FAQ.
• I have searched in existing issues.

Environment

• OS: Windows 11
• scrcpy version: win64-v2.4
• installation method: release x64
• device model: SM_G9550
• Android version: 9

Describe the bug
Several attempts to initialize the connection to the phone (through different commands) has failed. Phone detection and debug authorization worked properly (hopefully) but some googling on the error says that android may have just refused file access for being a new android version. Searching through other issues there are lots of other issues that includes "stream disabled due to connection error" but none were relevant. Included is the log for posting the recommended command listed in the project homepage:

On old Android versions, --keyboard=uhid cannot work due to permissions errors (like you get).

Thanks for the quick response! Removing --keyboard has made it work :)
